Abstract:
Tufted hairs, an unusual hair follicle dysplasia, are characterized by several hair shafts grouped together, emerging from a single hair follicle-like "doll's hair". This clinical picture is considered characteristic of folliculitis decalvans (FD). However, the emergence of grouped hair shafts from a single follicle can also be observed in other hair disorders, even if not as a distinctive diagnostic sign. This paper aims to collect and analyze all clinical and trichoscopic features of different hair diseases with tufted hairs to find distinctive features, helping the clinician with the diagnosis.
